    1. Hydrogen Storage

      Concentration-Dependent Dehydrogenation of Ammonia–Borane/Triglyme Mixtures (pages 49–54)

      Johannes F. Kostka, René Schellenberg, Felix Baitalow, Tom Smolinka and Florian Mertens

      Article first published online: 16 NOV 2011 | DOI: 10.1002/ejic.201100795

      Thumbnail image of graphical abstract

      Ex situ 11B NMR spectroscopic studies and gas volumetric analysis of the thermolysis reaction of ammonia–borane (AB) dissolved in triglyme (TG) reveal an unexpected but favourable concentration dependence of its dehydrogenation behaviour. In concentrated solutions of AB in TG, diammoniate of diborane was found in significant amounts similar to the solid state, yet the mechanism of AB decomposition differs.

    2. Nanocrystals for Thermoelectrics

      Synthesis and Characterization of Nanocrystalline FeSb2 for Thermoelectric Applications (pages 55–58)

      Anuja Datta and George S. Nolas

      Thumbnail image of graphical abstract

      The substitution of N2Py2 ligands with carboxylic functionalities affects the catalytic properties of a series of iron complexes. Selective epoxidation catalysis with H2O2 was obtained only when one carboxylic group was present in the ligand. The moderate (up to 40 %) enantioselectivity of the reaction with electron-rich/poor alkenes was also tuned by the presence of exogenous acids.
